Do not
raise the platform
unless the machine is on a
firm, level surface.
Do not depend on the tilt alarm as a level indicator.
The tilt alarm sounds on the chassis only when the
machine is on a severe slope.
If the tilt alarm sounds:
Lower the platform. Move the machine to a firm,
level surface. If the tilt alarm sounds when the
platform is raised, use extreme caution to lower
the platform.
Do not alter or disable the limit switches or angle
sensor.
Do not drive over 0.7 mph / 1.1 km/h with the
platform raised.
Do not use the platform controls to free a platform
that is caught, snagged, or otherwise prevented
from normal motion by an adjacent structure. All
personnel must be removed from the platform
before attempting to free the platform using the
ground controls.
Do not push off or pull
toward any object outside
of the platform.

Do not raise the platform when wind speeds may
exceed 28 mph / 12.5 m/s. If wind speeds exceed
28 mph / 12.5 m/s when the platform is raised,
lower the platform and do not continue to operate
the machine.
Do not operate the
machine in strong or gusty
winds. Do not increase the
surface area of the
platf
orm or the load.
Increasing the area
exposed to the wind will
decrease machine
stability.
Do not drive the machine
on or near uneven terrain,
unstable surfaces or
other hazardous
conditions with the
platform raised.
Use extreme care and slow speeds while driving
the machine in the stowed position across uneven
terrain, debris, unstable or slippery surfaces and
near holes and drop-offs.
Do not alter or disable machine components that
in any way affect safety and stability.
Do not replace items critical to machine stability
with items of different weight or specification.
Do not modify or alter a mobile elevating work
platform without prior written permission from the
manufacturer. Mounting attachments for holding
tools or other materials onto the platform,
toeboards, or guard rail system can increase the
weight in the platform and the surface area of the
platform or the load.
Do not place or attach
fixed or overhanging loads
to any part of this
machine.
Do not place ladders or
scaffolds in the platform or
against any part of this
machine.
Do not transport tools and materials unless they
are evenly distributed and can be safely handled
by person(s) in the platform.
Do not use the machine on a moving or mobile
surface or vehicle.
Be sure all tires are in good condition, air-filled
tires are properly inflated and lug nuts are properly
tightened.

Operation on Slopes Hazards
Do not drive the machine on a slope that exceeds
the slope and side slope rating of the machine.
Slope rating applies to machines in the stowed
position.

Note: Slope rating is subject to ground conditions
with one person in the platform and adequate
traction. Additional platform weight may reduce
slope rating. See Driving on a Slope in the
Operating Instructions section.
Fall Hazards
The guard rail system provides fall protection. If
occupant(s) of the platform are required to wear
personal fall protection equipment (PFPE) due to
job site or employer rules, PFPE and its use shall
be in accordance with the PFPE manufacturer’s
instructions and applicable governmental
requirements. Attach the lanyard to the anchor
provided in the platform.
Do not sit, stand, or climb
on the platform guard
rails. Maintain a firm
footing on the platform
floor at all times.
Do not climb down from
the platform when raised.
Keep the platform floor clear of debris.
Close the entry gate before operating.
Do not operate the machine unless the guard rails
are properly installed and the entry is secured for
operation.
Do not enter or exit the platform unless the
machine is in the stowed position.
Hazards related with the specific product
application of exiting at height have been
considered in the design of the machine, for
further information contact Genie (see section
Contacting the Manufacturer).

Collision Hazards
Be aware of limited sight
distance and blind
spots
when driving or operating.
Be aware of extended platform position when
moving the machine.
The machine must be on a level surface or
secured before releasing the brakes.
Operators must comply with employer, job site,
and governmental rules regarding use of personal

the platform controls and the platform decal plate
for drive and steer functions.
Do not lower the platform
unless the area below is
clear of personnel and
obstructions.
Limit travel speed
according to the condition
of the ground surface,
congestion, slope,
location of personnel, and
any other factors which
may cause collision.
Do not operate a machine in the path of any crane
or moving overhead machinery unless the controls
of the crane have been locked out and/or
precautions have been taken to prevent any
potential collision.

Bodily Injury Hazard
Always operate the machine in a well-ventilated
area to avoid carbon monoxide poisoning.
Do not operate the machine with a hydraulic oil or
air leak. An air leak or hydraulic leak can penetrate
and/or burn skin.
Improper contact with components under any
cover will cause serious injury. Only trained
maintenance personnel should access
compartments. Access by the operator is only
advised when performing a pre-operation
inspection. All compartments must remain closed
and secured during operation.
Component Damage Hazards
Do not use any battery or charger greater than
12V to jump-start the engine.
Do not use the machine as a ground for welding.
Do not operate the machine in locations where
extremely high magnetic fields may be present.
Explosion and Fire Hazards
Do not start the engine if you smell or detect liquid
petroleum gas (LPG), gasoline, diesel fuel or other
explosive substances.
Do not refuel the machine with the engine running.
Refuel the machine and charge the battery only in
an open, well-ventilated area away from sparks,
flames and lighted tobacco.
Do not operate the machine or charge the battery
in hazardous locations or locations where
potentially flammable or explosive gases or
particles may be present.
Do not spray ether into engines equipped with
glow plugs.

Damaged Machine Hazards
Do not use a damaged or malfunctioning machine.
Conduct a thorough pre-operation inspection of
the machine and test all functions before each
work shift. Immediately tag and remove from
service a damaged or malfunctioning machine.
Be sure all maintenance has been performed as
specified in this manual and the appropriate Genie
service manual.
Be sure all decals are in place and legible.
Be sure the operator's manual is complete, legible,
and in the storage container located on the
machine.
Crushing Hazard
Keep hands and limbs out of scissors.
Use common sense and planning when operating
the machine with the controller from the ground.
Maintain safe distances between the operator, the
machine and fixed objects.
Maintain a firm grasp on the platform rail when
pulling the rail pins. Do not allow the platform
guard rails to fall.
Outrigger Safety
Tip-over Hazards
Do not lower the outriggers unless the machine is
on a firm surface. Avoid drop-offs, holes, unstable
or slippery surfaces and other possible hazardous
conditions.
When the auto level function is not being used and
the outriggers are being lowered individually, the
steer-end outriggers must be lowered first.
Do not raise the platform unless the machine is
level. Do not set the machine up on a surface
where it cannot be leveled using only the
outriggers.
Do not raise the platform unless all four outriggers
are properly lowered, the footpads are in firm
contact with the ground and the machine is level.
Do not adjust the outriggers while the platform is
raised.
Do not drive while the outriggers are lowered.
